Answer:

7x-1

Step-by-step explanation:

14 + 7x - 15 = k

7x - 1 = k

Finding x,

14 + 7x - 15 = k

=> 14 + 7x = k + 15

=> 7x = k + 15 - 14

=> x = (k + 1)/7

So, 7 * (k+1)/7 - 1 = k

k + 1 - 1 = k

=> k = k

So the answer is true that 7x - 1

iragen [17]

Answer:

The correct evaluation is 1 1/3 (one and one-third) and not 16 and one-third

Step-by-step explanation:

The student was wrong in his evaluation because the correct result should be 1 1/3 (one and one-third) and not 16 and one-third

The expression '1/3 more than the product of four and a number' means

(4g + 1/3)

Evaluating the expression when g = 1/4

You will have

4×1/4 + 1/3

= 1/1 + 1/3

Find the LCM of 1 and 3 and add

= (3+1)/3

=4/3

= 1 1/3

The correct evaluation is 1 1/3 (one and one-third) and not 16 and one-third

"For which value of c does Limit of f (x) as x approaches c not exist?"
Damm [24]

The limit does not exist at the jump discontinuity at <em>x</em> = -2.

From the left, the green-ish curve approaches 4; from the right, the orange curve approaches 6. These one-sided limits are not equal, so the two-sided limit does not exist.

the constant value which is repeatedly added to each term in an arithmetic sequence to obtain the next term​
Mariulka [41]

Answer:

<h2>This value is called the common difference</h2>

Step-by-step explanation:

The common difference is the constant value which is repeatedly added to each term in an arithmetic sequence to obtain the next term​, it is basically the difference between consecutive numbers

To find the common difference we can subtract the previous term from the first time or the second to the last term from the last term, the idea of finding the common difference is basically subtracting the previous term form the subsequent term.
